Let me reiterate that nothing is being mounted here -- the device is not even being registered as a SCSI drive. Digging further in the archives, I just came across a long thread on unmount panics in freebsd-stable in July, including posts from you (Warner) acknowledging that it's a serious problem but saying fixing it will be horrendously difficult because of historical assumptions at all levels in the VM/buffer-cache/etc that "devices don't go away". But this doesn't seem to be that problem. I can't believe I'm the only one seeing it. If you can't reproduce it, I'm happy to mail you the device in question (which works nicely on linux and windows).
